GW,
To compare these two is a little creative to say the least. Jetbird plans to buy and operate aircraft, this other crowd seem to be offering the markets empty sectors from Avinode, one involves millions of pounds worth of investment and staff with the right skills to find work, and fly the aircraft, the other involves subscribing to Avinode.
In my opinion if the sum of £269 is mentioned in this market, it's normally the catering bill.
